Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Obtain a user access token with the channel:edit:commercial scope
Check the channel's current ad state before triggering a break to avoid an immediate rejection
Call POST https://api.twitch.tv/helix/channels/commercial with broadcaster_id and length (seconds) to start a commercial
Read the response's retry_after value to know when another ad break is allowed
Handle the enforced cooldown -- a new ad cannot be started until 8 minutes after the previous one
Known gotchas
The 8-minute cooldown is enforced server-side; retry logic should back off using retry_after rather than a fixed timer
The broadcaster_id in the token must match the target channel -- you cannot trigger commercials on a channel you don't own/moderate with the right token
